Abstract

The number of domestic e-commerce transactions has been breaking its own record by an annual average growth rate of over 20% based on volume for the past 5 years. Due to the rapid increase in e-commerce market, retail companies that have difficulty meeting consumers in person are in fierce competition to take the lead in the last mile service, which is the only point of contact with customers. Especially in the delivery area, where competition is most intense, the role of the fulfillment center is very important for service differentiation. It must be capable of fast product preparation ordered by consumers in accordance with the delivery service level. This study focuses on the order picking system for rapid order processing in the fulfillment center as an alternative for companies to gain competitive advantage in the e-commerce market. A mixed integer programming model was developed and implemented to optimize the stock replenishment in order picking facilities. The effectiveness was scientifically and objectively verified by simulation using the actual operation process and data.

국내 전자상거래는 거래액을 기준으로 최근 5년간 연평균 20% 이상의 성장률을 지속적으로 기록하고 있다. 전자상거래의 급증으로 인해 소비자를 직접 만나기 어려운 유통기업들은 고객과의 유일한 접점이 되는 라스트마일 서비스 경쟁이 치열한데, 특히 최근 가장 경쟁이 뜨거운 배송영역은 서비스 차별화를 위해 풀필먼트 센터의 역할이 매우 중요하다. 소비자가 주문한 제품을 서비스 수준에 맞춰 신속하게 준비 할 수 있는 역량을 반드시 갖추고 있어야 한다. 본 연구는 전자상거래 시장에서 기업이 경쟁력을 갖추기 위한 방안으로써 풀필먼트 센터에서의 신속한 주문처리를 위해 오더피킹 시스템을 대상으로 연구를 진행하였다. 오더피킹 설비에서의 재고 보충 최적화를 위한 수리 모형 알고리즘을 구현하고, 실제 운영 프로세스와 데이터를 활용한 시뮬레이션을 통해 과학적이고 객관적인 방법으로 효과를 검증하였다.
